Frequently Asked Questions
We're here to help with any questions you may have
What does it cost to get a heat pump cleaned?
A professional heat pump deep clean in the Nelson/Tasman region costs $169 for a single unit with EcoPure Heat Pump Tasman, or $149 per unit when we clean two or more on the same visit. This includes full casing removal, high-pressure coil and fan barrel cleaning, and a natural sanitising treatment.
How often should a heat pump be cleaned?
We recommend a professional deep clean once a year. Heat pumps run year-round in Nelson and Tasman, heating in winter and cooling in summer, so mould, dust and bacteria build up steadily on the coil and fan barrel. Homes near the coast or with pets may benefit from more frequent cleaning.
Can I clean my heat pump myself?
You can and should rinse the filters yourself every few weeks, it takes five minutes and keeps airflow healthy. But the coil and fan barrel, where mould and bacteria actually grow, sit behind the casing and require a full strip-down and high-pressure clean. That part is best left to a professional.
What is the average cost to service a heat pump?
A basic heat pump service, typically a filter rinse and quick wipe-down, usually costs $80 to $120 in New Zealand. A genuine deep clean, where the casing is removed and the coil and fan barrel are pressure-cleaned and sanitised, sits around $150 to $200. The two are very different jobs, so it pays to ask exactly what's included. At EcoPure Heat Pump Tasman we specialise exclusively in deep cleaning, so every visit is the full strip-down, never a surface wipe.
Why does my heat pump smell musty?
A musty or damp smell when your heat pump starts up usually means mould and bacteria have built up on the coil and fan barrel inside the unit. The coil stays damp after every cooling cycle, creating the perfect environment for growth, and the fan then blows those spores into your room. A filter rinse won't fix it, the smell comes from behind the casing. A professional deep clean removes the build-up at its source and sanitises the unit.
Can a dirty heat pump make you sick?
It can contribute to health issues, especially for people with asthma or allergies. A dirty heat pump circulates air over mould, bacteria and dust trapped on the coil and fan barrel, then pushes that air around your home for hours a day. Common signs include irritated eyes, sneezing, or allergy symptoms that ease when you leave the house. A deep clean and sanitise removes the build-up so your heat pump is circulating clean air again.
